Morning!
I've been using the 007 a lot Tom, almost all commercial work until now but grabbing a last minute flight to Iceland tomorrow as I need a break! I'm taking both cameras with me and will just be doing some personal work, can't wait!
The 007 has paid for itself already but had the S adapter for the SL been available at launch I may have gone the same way as Richard, it would certainly have been a tougher decision. As it is I think the 007 does everything the 006 does but faster and at higher ISO's but whether that is worth the cost of upgrade is a very personal thing. I think 006 used prices are crap so that makes it easier to keep mine as a backup, it has paid for itself many times over though so can't complain!
I alway read about peoples lists of wants from cameras and the additions to the 007 are welcome but I don't shoot it any differently to the 006, I used to use live view all the time with the Nikons and missed it when I went to S but now I have it I never use it on the 007, for my work it's just not necessary with the viewfinder being so good. The video has been useful and I have managed a couple of really nice interview shoots with it so there's a big benefit, the SL could have done that for sure. I absolutely love the DoF scale, as a confirmed hyperfocal focuser, I love it, so easy to get sharp shots when looking for everything in focus, should be even easier when the new firmware is released. Other than that, the whole camera is just much more responsive but I find start up time isn't much improved which is something that could definitely get better. The 007 hasn't lost any of that beautiful simplicity the 006 has, you can just shoot with it!
A couple of weeks in Iceland without thinking about work is something I'm really looking forward to, will give me a much better view on how the camera suits personal work, I'm done with buying kit for a while though, would rather spend the money on going to beautiful places instead now!
Good luck with your decision.
Mat
